Training Within Industry (TWI)

For companies unsatisfied with traditional training methods, TWI is an effective alternative that goes beyond the classroom and helps create a lasting Lean culture.

The people of Donnelly understand the benefits of this powerful process firsthand, and we’re eager to share our experience with others in industry. Team members have become certified trainers of Training Within Industry,
which focuses on the disciplines of Job Methods, Job Instruction and Job Relations, and have trained many others at Donnelly.

Fully integrated into our work environment, the TWI process continues to produce sustainable improvements for us and our customers.

Error Proofing

Unlike common mistake-proofing techniques that focus on the design phase or the manufacturing processes, our own error-proofing method helps reduce problems by focusing on the people factor.

We break down tasks and identify points where human interaction occurs, designing processes to standardize these activities and create more repeatable outcomes. As a result, employees learn how to take preventive measures that
decrease defects.

In one instance, parts rejection related to human error was reduced 75 percent year-over-year and parts-per-million defects reduced by two-thirds.
